BSA ACS run on SBSA Reference platform gives 8 skipped tests:
303 : Check SMMU Large Physical Addr Support
403 : Memory mapped timer check
404 : Generate Mem Mapped SYS Timer Intr
405 : Restore PE timer on PE wake up
505 : Wake from System Timer Int
606 : 16550 compatible UART
806 : Legacy int must be SPI & lvl-sensitive
817 : Check Direct Transl P2P Support
303 wants SMMU with LPA support but skips when cpu lacks it.
606 checks for 16550 UART, we have PL011 one (you need one of them)
403, 404, 405, 505 require memory mapped system timers which we do not
have. But we have PE timer always on (test 402) so can ignore them.
806 is platform specific and needs to be populated by partners with
system legacy irq map.
817 wants RP type device with P2P and ATS support. Skips if not present.
To support the removal of the DT in EDK2, we can parse the memory related information in TF-A and pass them to EDK2 through SMC.

Enable CPU cluster support on SbsaQemu platform, so that users can
specify a 4-level CPU hierarchy sockets/clusters/cores/threads. And this
topology can be passed to the firmware through DT cpu-map.

When SaSbQemu platform is configured with multi memory nodes, like
numa architecture, os will ignore any memory node in the device tree
except the first one.The kernel reads UEFI memory map for memory
information when booting via UEFI.However UEFI only allocates the
first memory node memory space for SbsaQemu platform, in this
scenario we can use the GCD services to add memory spaces
for high memory node.
Changes in v2:
- get the information of memory via SMC rather than FdtClientDxe.
- add a new driver rather than use HighMemDxe.

I have to skip tomorrow's (19th Dec) meeting. Zoom should allow to join
without me being present but I plan to have an alarm to be able to start
it in case of need.
SbsaQemu can configure with numa-related arguments, but OS cannot
identify the numa architecture without SRAT tables. We add supporting
for generating SRAT tables at runtime to solve this issue.
Changes in v2:
- get the information of numa via SMC calls rather than parse DT.
Changes in v3
- Considering the combination of CPU and memory nodes when counting
numa nodes.

We submit a patch in TF-A which is armed at reporting the information
of through SMC. Cooperating with that patch, we can get thecinformation
of memory in EDK2 via SMC calls.
Changes in v2:
- Align with the latest version.
- modify language and formatting errors.
Changes in v3:
- read the information of memory in SbsaQemuSmc.c.
Changes in v4:
- add DT fallback when SMC failed.
